Letters Patent No. 90,653, datellfzme 1, 18.69JH ill/j IMPROVEMENT IN GUANO-ATTACHMENT FOR `SIl-lEID--DRIIILIh The Schedule referred to in these Letters Patent Vand making part of the same.

To all whom it may conce/rn l Be it known that' I, JOHN F. Frsnnn, of Greencastle, in the county of Franklin, and State of Pennsylvania, have invented a new and useful Improvement in Guano-Attachments to l/Vheat-Drills; and 'I do hereby declare that the following is afull and exyact description thereof, reference vbeing had to the accompanying drawings, and to the letters of reference marked thereon.

My invention consists of an arrangement of coggearing, andv other devices for stirring guano and other fertilizers, the cog-gearing under the hopper being connected with and operating fingers, or stirrer in the hopper. l v

In the accompanying drawings- Figure l is an end view of the hopper of a guano` attachment to wheat-drills, with my improvements.

Figure 2 is a bottom view of the same. p

Figure 3 is a view of the inside of the hopper.

By means of thel gear-wheel A, motion is communicated to-the pinion B and the crank C, and by means of a connecting-rod, D, the rack-bar E receives a re- `ciprocatiug motion.

This rack-bar gears into a quarter-pinion, F, upon n. shaft, Gr, which extends up into the hopper, and carries lingers, or stirrers H and I, and thus motion is communicated from the rack-bar to the ngers, which stir the guano.

The feed-hole'in the bottom of the hopperis opened `and closed by means of two slides K L, and a lever,

N, (as shown mostly indotted lines, fig-2.)

The two slides, being pivoted to the lever N, the

feed-hole may be opened more or less, so as to feed fast or slow, or stop the feed, at pleasure. The two slides move in opposite directions, and thus the feed is always at the same point or centre, whether the feed is fast or slow.

In place of the quarterpinion F, a crank, or swinging arm may be used, the same being pivoted or connected with the reciprocating bar E, but I prefer the cog-gear above described.

Having thus described my invention,

. I claiml. The quartenpinion F and reciprocating rack-bar E, or their equivalents, placed under the hopper, in combination with the swinging fingers, or stirrers, inside ofthe hopper, substantially as set forth.

2. In combination with the stirrers and quarterpinion, the reciprocating bar E, the rod D, crank O, pinion B, and gear-wheel A, substantially as set forth.

JOHN F. FISHER.
